ABSTRACT:
A one-piece split shank through bore plastic screw grommet for use in a round hole and which will not spin when a screw is introduced into the bore. In this fastener the size of the shank exceeds the hole to such a degree that when a drive pin having crushable ribs is driven into the bore to expand the shank there are sufficient forces exerted on the wall of the hole to prevent rotation of the screw grommet when the torque of the screw is imparted to the grommet as threads are formed in the bore by the screw.
